Please explain that slowly for the slower of us, so we can follow your conclusion.

Agreed, but the driver typically makes decisions about forming commands
based on flags provided and suffixes to files.
(at least for the two I am familiar with) it does not do dependency analysis
nor does it have any need to parse the source.
I suspect it would be better to place the ‘trivial build’ system as a separate
entity (perhaps invoked by the driver) rather than upgunning the driver to
have those properties.
It's irrelevant, to this discussion, where you place such functionality if ultimately the compiler driver is the one providing the UI that people use.
